Qubit Scorecard

Quantum computing developments are moving quickly. Stay up to date with the race towards quantum supremacy with our quick reference report of qubit counts.

Not all qubits are created equal. There are many ways to harness qubits and build quantum computers that produce different qubit quality levels. When looking at the state of quantum computing hardware, it is important to take into account that there are many factors including coherence times, noise, and other measures that come together to give you physical qubit to logical qubit ratio. With that in mind, the following are the current and road mapped qubit counts from some of today’s most advanced quantum computer developers.

Updated July 2023


Leading, IBM holds the current title for quantum supremacy with 433 qubits.
Rigetti and IBM have aggressive roadmaps planned for the next two to four years with a goal for 4,000 qubits.

IonQ, ColdQuanta, and Fujitsu have roadmaps planned for slightly extend timelines with the goal of 1,000 qubits.
Google and PsiQuantum have longer term roadmaps for achieving 1 Million qubits before the end of the decade.

Several companies have promising architectures that may enable them to scale their qubit count rapidly.
